Last year the buzz was all about Functional programming, this year the buzz is about Reactive Programming. In 2016 the buzz was all about Functional programming. […]Continue reading
Out of the box, Spring Boot is very easy to use with the H2 Database. Spring programmers typically prefer writing code against such lightweight in-memory database, rather than on an enterprise database server such as Microsoft SQL Server or Oracle. In-memory databases come with several restrictions making them useful only in the development stages in […]Continue reading
I’ve been playing with Docker a lot recently to deploy Spring Boot applications. Docker is very cool. I’ve been learning a lot about it. This is my unofficial Docker Cheatsheet. Use with caution! Got any tips and tricks? Comment below, and I’ll try to update this. List all Docker Images docker images -a List All Running […]Continue reading

Spring Boot makes it extremely convenient for programmers to quickly develop Spring applications using an in-memory database, such as H2, HSQLDB, and Derby. These databases are lightweight, easy to use, and emulates other RDBMS with the help of JPA and Hibernate. Obviously, they don’t provide persistent storage; but they a fast way to test persistent functions […]Continue reading
A real common task is to display a list of objects fetched from the database in a HTML table on a webpage. Thymeleaf has a handy tag which allows us to iterate over a list of objects, and generate HTML code to display a table row for each object. The HTML generated really does not “need” […]Continue reading
